RESUMO

OBJECTIVE: To assess the efficacy and safety of prenatal dexamethasone treatment in offspring at risk for congenital adrenal hyperplasia. METHODS: MEDLINE, EMBASE, the Cochrane Library, the clinicaltrials.gov website databases were systematically searched from inception through March 2019. WMD and SMD with 95%CIs were calculated using random or fixed effects models. RESULTS: There was a significant reduction in virilization in the DEX-treated group (WMD: -2.39, 95%CI: -3.31,-1.47). No significant differences were found in newborn physical outcomes for birth weight (WMD: 0.09, 95%CI: -0.09, 0.27) and birth length (WMD = 0.27, 95%CI: -0.68, 1.21). Concerning cognitive functions, no significant differences in the domains of psychometric intelligence (SMD: 0.05, 95%CI: -0.74, 0.83), verbal memory (SMD: -0.17, 95%CI: -0.58, 0.23), visual memory (SMD: 0.10, 95%CI: -0.14, 0.34), learning (SMD: -0.02, 95%CI: -0.27, 0.22) and verbal processing (SMD: -0.38, 95%CI: -0.93, 0.17). Regarding behavioural problems, no significant differences in the domains of internalizing problems (SMD: 0.16, 95%CI: -0.49, 0.81), externalizing problems (SMD: 0.07, 95%CI: -0.30, 0.43) and total problems (SMD: 0.14, 95%CI: -0.23, 0.51). With respect to temperament, no significant differences in the domains of emotionality (SMD: 0.13, 95%CI: -0.79, 1.05), activity (SMD: 0.04, 95%CI: -0.32, 0.39), shyness (SMD: 0.25, 95%CI: -0.70, 1.20) and sociability (SMD: -0.23, 95%CI: -0.90, 0.44). CONCLUSIONS: Prenatal DEX treatment reduced virilization with no significant differences in newborn physical outcomes, cognitive functions, behavioural problems and temperament. The results need to be interpreted cautiously due to the existence of limitations.

RESUMO

Background Steroid 21-hydroxylase deficiency is an autosomal recessive disorder, present in 90-95% of all cases with congenital adrenal hyperplasia (CAH). The classical simple virilizing (SV) form of the disease causes virilization of the external genitalia in newborn females and pseudo-precocious puberty in both sexes, due to reactive androgen overproduction. Case presentation We describe a 3.5-year-old girl presenting with pubarche, P2 according to Tanner, advanced bone age of 6 years and 10 months, and high serum levels of 17-hydroxyprogesterone (17-OHP). Molecular analysis of the nine most common pseudogene-derived CYP21A2 point mutations was performed in the patient and her family members using the polymerase chain reaction/amplification-created restriction site (PCR/ACRS) method. We detected the P30L/I172N genotype in the patient. She had inherited a mild P30L mutation from her mother and a severe I172N mutation from her father. Conclusions Although the CAH phenotype is determined by the allele that produces most of the enzyme activity and the mild non-classical (NC) phenotype should be expected, the mild P30L known to be more virilizing probably induced the classical SV phenotype in our patient. A continuous regimen of hydrocortisone at a recommended dose failed to decrease the 17-OHP sufficiently. Careful tapering of the dose did not help, and her pubic hair advanced to P3 according to Tanner. Individually tailored treatment is warranted in this patient.

RESUMO

Congenital adrenal hyperplasia (CAH) due to 21 hydroxylase deficiency is a genetic disorder that leads to hypocortisolism, hyperandrogenism and, in the most severe forms, also to hypoaldosteronism. Girls with classic CAH are born with virilized external genitalia. Prenatal dexamethasone (DXM) treatment can reduce virilization but may have side effects for mother and fetus. We present the first case of a girl who was born with CAH and an orofacial cleft. She was treated with prenatal DXM to prevent virilization. Oral clefts have to be considered as a potential side effect of prenatal DXM treatment.

RESUMO

In this study, a GnRH agonist, leuprolide acetate (LA), was given as a single depot injection before 48 h of life to Wistar female rats allotted to prenatal (E16-18) and postnatal androgenization (day 5 of life) by the use of testosterone propionate, looking for reproductive endpoints. Remarkably, a single injection of LA increased the estrus cycles in the postnatal group (PostN) from 0% to 25% of the estrus cycles in the postnatal LA treated group (PostN L). LA also reduced the serum testosterone levels and cysts and atretic follicles in PostN L in contrast with rats (>100 days) from the PostN group (p = 0.04). Prenatally androgenized rats (PreN) exhibited significant modifications in the hypothalamic genes, such as Gnrh. To the best of our knowledge, this is the first study to show that blockage of the GnRH axis with leuprolide acetate depot prevented the development of typical features (anovulation, cysts, atretic follicles) in a postnatal testosterone propionate rat model of PCOS.

RESUMO

CONTEXT: Dexamethasone (DEX) is used to prevent virilization in female fetuses at risk of congenital adrenal hyperplasia (CAH). Given that treatment has to be started before the genotype is known, 7 out of 8 fetuses will be exposed to DEX without benefit. OBJECTIVE: To evaluate long-term cognitive effects of prenatal DEX therapy in healthy (non-CAH) DEX-treated children. DESIGN AND SETTING: Observational study with patient and control groups from a single research institute. PARTICIPANTS: Healthy (non-CAH) DEX-treated subjects (n = 34) and untreated population controls (n = 66) from Sweden, aged 7-17 years. INTERVENTION: DEX-treatment used in unborn children at risk of CAH, during first trimester of fetal life. MAIN OUTCOME MEASURES: Standardized neuropsychological tests and questionnaires were used. RESULTS: DEX treatment has widespread negative effects in girls. In Wechsler Intelligence Scales for Children-III scale subtests, we observed significant interactions between DEX and GENDER (coding, P = .044; block design, P = .013; vocabulary, P = .025) and a trend for the subtest digit span (P = .074). All interactions were driven by DEX effects in girls, but not boys, with DEX-treated females showing lower scores than female untreated controls (coding, P = .068, d = 0.66; block design, P = .021, d = 0.81; vocabulary, P = .014, d = 0.84; digit span, P = .001, d = 1.0). Likewise, DEX-treated girls tend to have poorer visual spatial working memory performance than controls (span board test forward: P = .065, d = .80). We observed no effects on long-term memory, handedness, speed of processing, nor self-perceived or parentally reported scholastic performance. CONCLUSIONS: Early prenatal DEX exposure affects cognitive functions in healthy girls, ie, children who do not benefit from the treatment. It can therefore not be considered safe to use this therapy in the context of CAH.

RESUMO

OBJECTIVE: To describe the action of prenatal dexamethasone (PreDex) on the anatomy of female congenital adrenal hyperplasia (CAH) genitalia when started at later stages of gestation. MATERIALS AND METHODS: Our group follows a large cohort of French CAH patients who underwent PreDex therapy, of whom 258 were recently reported. Four 46,XX patients with a delayed PreDex treatment presented with a virilized genitalia and required surgical reconstruction. This is a retrospective report on genital phenotyping at the time of surgery of these four patients who began PreDex therapy at 8, 12, 20, and 28 weeks of gestation. RESULTS: Although this series is limited in number, the anatomical description of the length of the genital tubercle, the height of the urethra-vaginal confluence, and the degree of fusion of the genital folds seems to be dependent upon the starting date of PreDex. Most PreDex treatments prescribed up to now have covered the full duration of gestation. CONCLUSIONS: Our findings suggest that PreDex therapy could be limited to the period of the partitioning window. It is hoped that further prospective multicentric clinical studies will obtain ethical approval in order to elucidate the place and protocols of PreDex therapy in the management of CAH.

RESUMO

Adrenocortical carcinomas (ACCs) are a rare entity, with an incidence of 1.5 per million population per year. The prognosis of ACC is poor. Complete surgical resection is essential for a curative approach and significantly determines overall prognosis. Tumor resection is sophisticated and complicated by the vulnerability of the tumor and its invasive growth. Chemotherapy and Mitotane are additional therapeutic approaches that are combined with surgery in an interdisciplinary strategy. In this study, 59 patients between 2 months and 18 years of age with histologically verified ACC were analyzed retrospectively with respect to oncosurgical aspects. Patients were registered in the GPOH-MET 97 trial of the Society of Pediatric Oncology and Haematology. Preoperative management, factors influencing surgical severity, and operative complications were assessed.The gender ratio was 1:2 (m:f). A total of 58 patients showed increased hormonal activity and associated clinical signs of hormonal excess. Tumor volume was ≥ 300 mL in 25 patients. These patients showed an increased rate of operative complications and a poorer overall survival (OS) rate (p<0.01). A total of 14 patients showed metastatic spread, particularly to the lungs and lymph nodes. Biopsy of the tumor was performed in 12 patients. Tumor rupture occurred in 11 patients. Preoperative biopsy and/or experienced tumor rupture were associated with poorer OS rate. R2 resection only was achievable in 5 patients, and surgery was not feasible in 3 patients.In conclusion, since most of the pediatric ACC are hormone active and can be diagnosed clinically, the need of a tumor biopsy has to be discussed critically. Thorough pre- and perioperative management is essential for oncosurgical success.

RESUMO

BACKGROUND: This prospective noninterventional study assessed the contraceptive efficacy, safety and the effects on signs of androgenization of the generic oral contraceptive containing 2 mg chlormadinone acetate/0.03 mg ethinylestradiol (CMA/EE) in a real-world setting. STUDY DESIGN: A total of 1440 women were investigated during a six-cycle period by 229 gynecological practices throughout Germany. RESULTS: The adjusted Pearl index was 0.136 (unadjusted: 0.271). Of 463 patients with cycle irregularities at baseline, 83.4% had regular cycles after six cycles. Likewise, 74.1% of 162 patients with spotting or breakthrough bleeding at baseline were free from these symptoms at the end of study. The percentage of patients with dysmenorrhea decreased significantly from baseline (36.5%) to visit 3 after six cycles (12.3%; p=.0001), with a significant reduction in the use of pain medication (p<.0001). Additionally, the number of patients with skin and hair problems was significantly reduced (skin: 56.3% at baseline, 19.6% after six cycles; hair: 45.7% at baseline, 13.4% after six cycles; p=.001). CMA/EE was well tolerated by the patients, and 89.44% of the gynecologists were satisfied with the treatment. CONCLUSION: Generic CMA/EE exhibits very good contraceptive efficacy, cycle control and dysmenorrhea reduction. Furthermore, treatment with generic CMA/EE led to a favorable reduction of skin and hair problems in our study.

RESUMO

Besides the contraceptive effect of the various hormonal contraceptives, it is intended to demonstrate the non-contraceptive health benefits for treatment and prevention of bleeding problems, menstruation-related pain and other disorders, such as premenstrual syndrome and signs of androgenization. The effectiveness can be improved by choosing the proper progestogen with antiandrogenic action. Treatment but also prevention can be achieved with hormonal contraceptives in benign proliferative diseases of women, such as ovarian cysts, endometriosis, adenomyosis, endometrial hyperplasia, myoma and benign breast disease. Furthermore, hormonal contraceptives such as estrogen/progestogen combinations reduce pelvic inflammatory disease, rheumatoid arthritis, asthma symptoms and preserve bone density. In addition, a major impact in oncological prevention seems to be possible for ovarian, endometrial and colon cancer and these positive preventive effects seem to persist also after discontinuation of hormonal contraceptives. In addition, practical concepts for hormonal contraceptive selection will be outlined.

RESUMO

17-ß-Hydroxysteroid dehydrogenase type 3 (17ßHSD-3) deficiency is a rare, but frequently misdiagnosed autosomal recessive cause of 46,XY disorder of sex development (DSD). 17ßHSD-3 enzyme is present almost exclusively in the testes and converts Δ4-androstenedione (Δ4) to testosterone (T). The diagnosis can be easily missed in early childhood as the clinical presentation may be subtle. Any young girl with an inguinal hernia, mild clitoromegaly, single urethral opening or urogenital sinus should raise suspicion. If not diagnosed early, patients present with severe virilization and primary amenorrhea in adolescence and may undergo a change from a female to male gender role. A low T/Δ4 ratio on baseline or hCG (human chorionic gonadotropin)-stimulated testing is suggestive of 17ßHSD-3 deficiency. The diagnosis can be confirmed with molecular genetic studies. This review summarizes the clinical presentations, reported mutations, diagnosis, treatment and clinical course of this disorder. The Arg80 site in exon 3 is the most common location of repeated mutations and can be considered a hot spot in certain Arab populations.

RESUMO

AIM: Testosterone treatment is essential for the induction and maintenance of virilization of female-to-male transsexuals. This study tested the suitability of a novel testosterone preparation for this purpose. METHODS: Parenteral long-acting testosterone undecanoate (TU) was administered to 12 female-to-male transsexuals. Observations were made while subjects received treatment. MAIN OUTCOME MEASURES: Virilization of female-to-male transsexuals and side effects of testosterone administration. RESULTS: The testosterone levels were largely identical to those in hypogonadal men receiving testosterone treatment with TU. There were no side effects. There was a small but significant decrease in plasma cholesterol and low-density lipoprotein, but plasma high-density lipoprotein did not change significantly. Both levels of hemoglobin and hematocrit rose upon administration but remained within the physiological range. CONCLUSIONS: TU is suited for induction of virilization in female-to-male transsexuals without significant side effects.

RESUMO

CONTEXT AND OBJECTIVE: In Sweden, from 1985 through 1995, 40 fetuses at risk for congenital adrenal hyperplasia (CAH) were treated with dexamethasone (DEX) to prevent virilization of affected females. We report long-term effects on neuropsychological functions and scholastic performance of this controversial treatment. DESIGN AND PATIENTS: Prenatally treated children, 7 to 17 yr old, were assessed with standardized neuropsychological tests (A Developmental Neuropsychological Assessment and Wechsler Intelligence Scales for Children) and child-completed questionnaires measuring self-perceived scholastic competence (Self-Perception Profile for Children). A parent-completed questionnaire (Child Behavior Checklist/4-18 School Scale) was used to evaluate whether the treatment had any impact on the children's school performance. In addition, a child-completed questionnaire measuring social anxiety (The Social Anxiety Scale for Children-Revised) was completed by the prenatally treated children aged 8 to 17 yr (n = 21) and age- and sex-matched controls (n = 26). RESULTS: Of 40 DEX-treated children, 26 (median age, 11 yr) participated in the study. Thirty-five sex- and age-matched healthy children were controls. There were no between-group differences concerning psychometric intelligence, measures of cerebral lateralization, memory encoding, and long-term memory. Short-term treated, CAH-unaffected children performed poorer than the control group on a test assessing verbal working memory (P = 0.003), and they rated lower on a questionnaire assessing self-perception of scholastic competence (P = 0.003). This group also showed increased self-rated social anxiety assessed by The Social Anxiety Scale for Children-Revised (P = 0.026). Prenatally treated, CAH-affected children performed poorer than controls on tests measuring verbal processing speed, although this difference disappeared when controlling for the child's full-scale IQ. CONCLUSIONS: This study indicates that prenatal DEX treatment is associated with previously not described long-term effects on verbal working memory and on certain aspects of self-perception that could be related to poorer verbal working memory. These findings may thus question future DEX treatment of congenital adrenal hyperplasia. Therefore, we encourage additional retrospective studies of larger cohorts to either confirm or challenge the present findings.

RESUMO

The treatment of congenital adrenal hyperplasia (CAH) before birth was instituted 20 years ago in an attempt to prevent virilization of the external genitalia in affected girls. Maternally administered dexamethasone, which readily crosses the placenta unaltered, is started very early in pregnancy to ensure adequate suppression of the fetal hypothalamo-pituitary-adrenal axis. Since the diagnosis cannot be ratified until chorionic villus sampling is performed 6 weeks later, fetuses that do not require treatment (all males and unaffected females) are also exposed to high-dose glucocorticoids for an interim period. It is not known whether this induces fetal programming of metabolic changes that may manifest as disease in adult life. The expected outcome at birth in a female fetus with CAH who has been treated with adequate amounts of dexamethasone is normal-appearing genitalia or at least a significant reduction in virilization for which genitoplasty is unlikely to be required. Short-term follow-up studies in infants and children exposed to dexamethasone indicate normal growth and development. The medical treatment of CAH before birth is a unique example of the successful prevention of a major congenital malformation. However, there is a potential concern about possible long-term consequences of exposure of the fetus to glucocorticoids during early embryogenesis and beyond. This mandates the need for prenatal treatment for CAH to be undertaken only in protocol-driven clinical trials that are obliged to follow all children exposed in utero for the long term in order to collect any evidence of adverse neurodevelopmental and metabolic consequences.

RESUMO

A 57-year-old woman presented with an apparently obvious diagnosis of iatrogenic virilization. At the age of 51, she began a 4-year treatment with prednisone or cyclosporine, which are known to promote hair growth, for Behçet disease. At the age of 56, osteoporosis was overtreated with the anabolic steroid nandrolone. Insignificant inhibition by dexamethasone of the extremely high serum concentrations of testosterone and less high concentrations of weak androgens prompted us to search for a virilizing tumor. Computed tomography showed a 2.3 x 1.5 cm nodule in the right adrenal gland. As the patient refused surgery, virilization was treated with the antiandrogen cyproterone acetate (CPA), but for only 4 months because clinical and hormone abnormalities reversed and the tumor was no longer visible. The patient remains symptom-free. This first report of a curative effect of CPA on a purely virilizing adrenal tumor opens new avenues in the management of such tumors.

RESUMO

Lipid cell tumors are a very small group of ovarian neoplasms. Especially rare they occur simultaneous in the both ovaries. They are connected with symptoms of virilisation and increased androgens serum concentration. This report describe a case of 34-years old woman with a symptoms of a quickly increased hirsutism and ascites. These symptoms were connected with recurrence of a lipid cell tumor in a left ovary after 4 years from ovariectomy on the other side. The diagnostic and therapeutic management in the regional hospital, where the first ovariectomy was performed, was not correct. Young women should be treated in a special gynecology departments, where pathological intraoperative diagnosis of the second ovary is possible. Quickly diagnosis and surgical treatment allowed to cure the patient. Follow-up examinations after 5 months showed symptoms resolved and normalization of serum androgens concentration. Diagnosis of these ovarian tumors is difficult but we should think about it in every case of androgenization. Analysis of the symptoms and quickly diagnosis gives a chance of entire treatment.

RESUMO

The finding of a serum testosterone level greater than 200 ng/dl in a woman with virilization raises concerns about an androgen producing tumor. This case report demonstrates that chronic annovulation in association with insulin resistance can cause significant elevations in the level of serum testosterone, and describes the therapeutic benefit of insulin sensitizing agents in reversing hyperandrogenemia.
